IMPROVEMENT IN DIES FOR CUTTING BOOT AND SHOE RA NDS.

Specification forming part of Letters Patent No. 164,963, dated June 29,1875 application filed February 27,187 5.

To all whom it may concern:

Be it known that 1, CHARLES H. BRIGHAM, of Marlborough, in the county ofMiddlcsex and State of Massachusetts, have invented a new and valuableImprovement inDies for Cutting Boot and Shoe Bands; and I do herebydeclare that the following is a full, clear, and exact description ofthe construction and operation of the same, reference being had to theannexed drawings, making a part of this specification, and to theletters and figures of reference marked thereon.

Figure 1 of the drawing is a representation of. a plan view of my die,and Fig.2 is a sectional view of the same.

This invention has relation to devices for cutting boot and shoe rands;and the nature of the invention consists in two or more horseshoe-shapedblades, arranged, the one within the other, at a suitable distanceapart, the said blades having end cutters and an ejector actuated bysprings arranged between the said blades, as will be hereinafter morefully described. In the annexed drawings, A A designate twohorseshoe-shaped cutting-blades, having chisel-edges a. Blade A isrigidly but remov ably secured to a strong metallic plate, B, into whichis socketed or otherwise suitably se cured a handle, 0, blade A beingarranged within blade A and rigidly secured to a plate, J, which is thenremovably attached in any convenient manner to plate B.

Then the die thus formed is forcibly brought down upon a piece ofleather or leather board the blades A A will cut out of the body of thesame a horseshoe-shaped blank, commonly known to the trade as a rand,and when two or more pieces of leather are arranged one above the otheran equal number of blanks will be simultaneously formed. The contiguousends of cutters A A being connected by chisel-edged cutters b, theblanks will be turned out complete and ready for use.

D represents a third horseshoe-shaped blade, rigidly secured to a plate,L, which blade is arranged within blade A, and is removably attached inany suitable manner to plate J. The cutting-edge of this blade is flushwith those of cutter-blades A A, and when it is fixed in position, asabove described, two sizes of rands are cut out at one and the same timeby a single stroke, the outer edge of the smaller rand being cut by theintermediate blade A. A recess or depression, 0, is cut in the end ofthe device, for the purpose of conveniently extricating the inner orsmaller rand; but for the purpose of removing the larger rand I use apreferably metallic horseshoe-shaped plate, F, of such dimensions thatit shall be received between cutter-blades A A in the position shown inFig. 1. This plate is provided with a suitable number of rods, d,projecting upwardly therefrom, ,upon which are arranged helical springss, and which pass through metallic guides c, rigidly secured to theouter edge of cutter A, and are held to their engagement therewith bymeans of a pin, 19, or a nut applied upon their upper screw-threadedends.

' When the blades A A are brought forcibly down upon the leather to becut into rauds by an y suitable motor the ejector-plate will yield,allowing the rand to be received between them; but the moment the dieisraised the recoil of the said spriu gs will force the blank outward frombetween the said cutters, which latter will be then ready for a secondcutting.

When it is desirable to cut a blank or rand of a single size the innercutter I) may be de tached, and the remaining cutters A A alone willthen beoperated.

What I claim as new, and desire to secure by Letters Patent, is-

In an apparatus for cutting heel-rands for boots and shoes, thecombination of a series of semicircular cutters, A A, end cutters b b,and spring-ejector F, adapted to cut at one operation rands varying insize, substantially as described.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

CHARLES H. BEIGHAM.
